Our van has been running hotter than normal and we had taken the thermasat out.We have been told you can run it without one and that you have to have one in.Which is true?
Now it stays hot and our tranny is taken forever to get up to speed
we checked the catalytic converters and one was clogged...we fixed that problem,but due to the clog could we been having MAP or some other sensor problem ?
And could the running hot be causing our tranny problems??
If not what could it be
We do not have the funds to take to a repair shop and we have 3 kids and this is our only car!!!!

PLEASE HELP
Thanks,
Rae

if you had a transmission problem it would more than likely be in the form of a slipping or not shifting properly another problem with those transmissions is when you go from an idle to pull out the tranmission bangs into gear because the oil pressure leaks past the accumulator piston.
if you have trouble with a loss of power and getting the vehicle rolling it could be any one of several issues with the engine, ranging from a blocked fuel filter to blocked converter.
you mentioned already that you solved a problem with a blocked cat but if your problem solver was a piece of bar that punched out your cat than thats what started your problems now.
without the heat from a properly workin cat the O2 sensors cant function right and this throws off the whole fuel to air ratio because the computer doesnt have a proper reading anymore.

Your questian about the thermasat, you do need one in this truck, a 195 degree. It goes along with what 351w said, if things are not right she will not run right.
